Supply Chain as a Control Problem Today’s forces of interest for the supplier,
manufacturer, and customer require ever-
increasing levels of supply chain agility and
inventory management to continuously
improve operational effi ciency. As these
forces interact across the supply chains,
further refi nement of standards in the areas
of sensing, measurement, communication,
control, decision policy, organizational
structure, practitioner responsibility, and
implementation practices are required to
move supply chain metrics of interest to
new levels of performance and reliability.
Grand Control Challenge
Well-controlled supply chains can deliver
the right product •
in the right quantity, •
from the right sources, •
to the right destinations, •
in the right quality/condition, •
at the right time, •
for the right cost;•
while
reducing inventories,•
increasing supply chain agility,•
reducing operational cycle time,•
optimizing supply product mix relative to the demand mix, and•
enabling maximum business profi tability.•

Nature of Supply Chain
Multiple Ownership: A company’s performance
in the supply chain is affected by its suppliers,
customers, suppliers’ suppliers and customers’
customers, and its collaboration with them. Each
company has a vested interest in all the links in
the supply chain, not just those of direct suppliers
and customers.
Constant Evolution: Products and equipment in
the supply chain may run their complete life cycles
as the overall performance is being improved.
Fast ramp-up and ramp-down of products, and
their accompanying processes and toolsets, pose
challenging transition problems.
Uncertain Dynamics: Supply chains are
stochastic, nonlinear, and time varying. In addition
to transport and throughput times being affected
by “simple” logistical and manufacturing systems
and related processing loads, they are affected by
